Should You avoid moderate workouts? Polarized training, hormones, and recovery

Stacy illustrates this with a friend’s workout: a finisher after upper body work. One person did a 1-min all-out ski erg while the partner did a heavy farmer’s carry, then they switched. They did 4 rounds, rested, then did 2 more rounds. By not going straight through, each 1-min effort was at peak intensity. She contrasts this with the typical approach of pushing through 6 rounds; by the end, the person would be too fatigued to hit the needed power output, turning the last rounds into moderate work that doesn’t drive adaptation. The core philosophy: quality over quantity, making every rep count.

Stacy presents this split as the physiologically ideal baseline when time is scarce. It covers both strength and cardiovascular conditioning through truly polarized efforts. The HIIT and SIT days ensure that the high-intensity work is distinct and recoverable, while the heavy lifting builds muscle and bone density. If a woman does additional classes like boot camp, Stacy advises making those classes serve as one of these designated days—for example, by making a boot camp class a strength day via heavier weights or an intensity day via movement efficiency—rather than simply adding them on top and risking overtraining.

Stacy acknowledges that boot camps are often a woman’s ‘soul food’ for social connection and mental release, so she does not advocate quitting. Instead, she arms participants with the concept of making the class work for your body. By choosing heavier loads and fewer reps, you move the session toward a strength-stressor. By choosing lighter loads and executing movements as explosively and efficiently as possible, you make it a high-intensity sprint day. This way, the class serves a defined physiological role in the weekly plan, rather than becoming another exhausting but unfocused effort.

Orange Theory is built around heart rate zones, and many women end up in a persistent moderate zone without a clear peak. Stacy suggests using the treadmill block to hit genuine high intensity, leveraging the ‘splat points’ system to ensure you’re above threshold, and then dialing back the strength portion to functional movement work so that the day is primarily a HIIT session. Alternatively, some days you can use the treadmill as a low-intensity warm-up and then go heavy or hard on the strength floor, making it a strength day. This rotation allows the same class to fulfill different roles in a weekly polarized plan.

Stacy argues that women, especially from their mid-30s onward, default to exhausting moderate-effort workouts, assuming no pain means no gain. Instead, she proposes a polarized approach: very low intensity serves as recovery, while very high intensity intervals—with full recovery between efforts—ensure each repetition hits the targeted intensity to create an adaptive response. She gives the example of a friend who did 4 rounds of 1-minute max-effort ski erg, then a break, then 2 more rounds, stopping before intensity dropped. If they’d pushed through 6 continuous rounds, the last 3 would have been sub-maximal and thus non-adaptive. The goal is stress that the body can clearly respond to, not volume for its own sake.

Stacy acknowledges that in an ideal training world, women wouldn’t do these classes at all—2 heavy lifting days, 1 HIIT, and 1 SIT per week would be optimal. However, she recognizes the immense value of social connection, accomplishment, and mental release these classes provide. Instead of quitting, she urges women to make the class work for their body: in boot camp, do fewer reps with heavier weight to make it a strength session, or use a day to focus purely on high intensity by moving efficiently with lighter loads. For Orange Theory, treat the treadmill 'splat points' as the dedicated high-intensity portion while the strength block becomes functional movement practice, or on another day use the treadmill as a warm-up and really go after the strength training. The underlying principle is that you are paying for the class, so you have the right to modify. It requires self-confidence to break from the group norm, but it gives you ownership over your results.
